According to Cato (Moro Swords) the type 1 is the earliest and your classification would seem correct. All but the last 2 are Sulu, with the last 2 being Maguindanao and perhaps Maranao respectively. The last one is very recent.
You could do a search on this forum for this type of discussion in the past 5 years - very lively and informative. Also reading Cato's book would be a great starter as well.
Welcome to the forum and a great question.
